This fully revised second edition of Jeff Bozanic's Mastering Rebreathers is a comprehensive new look at rebreathers, written for the diving industry. Its chapters cover all types of rebreathers currently available; the history, physics, physiology, and theory of rebreather diving; pre-dive, dive, and post-dive procedures; and maintenance and travel considerations. It is designed for use as a generic textbook for all agencies and rebreathers. Mastering Rebreathers, Second Edition is the perfect tool for those who would like to experience the thrill and excitement of expanding their diving skills and re-invigorating their passion for diving. In well-trained and well-informed hands, a rebreather will not only enhance the capabilities and enjoyment of diving, but will increase safety as well. Whether you are new to rebreathers and are using this book as part of a formal training course; if you've been diving with rebreathers for years and have bought this book to add to your library; or even if you are just curious to learn more about this exciting form of underwater life-support, you will find enormous value in the meticulously updated Mastering Rebreathers.

This updated and revised second edition of John Heine's Scientific Diving Techniques covers the details of research methods underwater. Included are general scientific diving guidelines, an overview of aquatic habits and ecosystems, specialized diving equipment and procedures, locating and marking study sites, archaeology, measuring physical and biological factors, underwater experimentation and underwater photographing and videography for the scientist. There are over 500 references to original scientific techniques. Also included are training exercises to aid Diving Safety Officers in training scientific divers.

Diving Science...Revisited is like no other diving text, including its predecessor, Diving Science. Amplified with figures, tables, and photos in color, this book includes four unique and innovative parts amplified by nine contributors. - Medical problems of diving (MPD) are discussed from stimulus-response perspectives in the phase of a dive in which they are likely to occur. - MPD are explained by how they affect the human diver whether physical, physiological, psychological, and/or lack of awareness. - A variety of diving types and situations from breath-hold to rebreather, from children to women to older aged adults, from cold water to cave, and from deep altitude to diving with handicaps are described in individual chapters with their merits, hazards, and necessary precautions for safe diving. - Part IV contains a concise summary of the MPD from seven different perspectives ranging from the significance of the problem to when to return to diving. - Part V consists of a rhetorical question for each of the first four parts with bullet points that recap the subjects covered in each chapter. This book describes the positive as well as undesirable ways divers' interact with the aquatic environment. It is especially recommended for the following: -Diving instructors and supervisors - Those involved with clinical applications of hyperbaric oxygen therapy - Those engaged in diving-associated marine biology and underwater missions - All divers, whether novice or advanced, who want to advance their knowledge about the science and medical challenges of diving.

This book summarizes what is known about mesophotic coral ecosystems (MCEs) geographically and by major taxa. MCEs are characterized by light-dependent corals and associated communities typically found at depths ranging from 30-40 m. and extending to over 150 m. in tropical and subtropical ecosystems. They are populated with organisms typically associated with shallow coral reefs, such as macroalgae, corals, sponges, and fishes, as well as specialist species unique to mesophotic depths. During the past decade, there has been an increasing scientific and management interest in MCEs expressed by the exponential increase in the number of publications studying this unique environment. Despite their close proximity to well-studied shallow reefs, and the growing evidence of their importance, our scientific knowledge of MCEs is still in its early stages. The topics covered in the book include: regional variation in MCEs; similarities and differences between mesophotic and shallow reef taxa, biotic and abiotic conditions, biodiversity, ecology, geomorphology, and geology; potential connectivity between MCEs and shallow reefs; MCE disturbances, conservation, and management challenges; and new technologies, key research questions/knowledge gaps, priorities, and future directions in MCE research.
